Non-generic collection - can hold a primitive or not?

Hi,
In K&B 6 book page no. - 597 under topic - The Legacy Way to Do Collections, it is written that A non-generic collection is quite happy to hold anything that is NOT a primitive.
Whereas the following code works fine.

Please tell me is this an error in the book or I am misunderstanding something?

Remember auto-boxing. It looks like you're adding an int to the collection, but it's actually being converted to an Integer first.

Oh yes...didn't thought about it.
Thanks Matthew
